Which type of training alternates high intensity with recovery?

The correct answer is interval training, which specifically focuses on alternating between periods of high-intensity effort and designated recovery periods. This type of training maximizes cardiovascular and muscular adaptations by pushing the body through bursts of intense exercise followed by rest or lower-intensity activity. This method not only enhances overall fitness levels but also improves endurance and allows for the efficient use of energy.

Resistance training typically involves lifting weights or performing bodyweight exercises with the goal of building strength and muscle mass, but it does not inherently include the structure of alternating intensity and recovery like interval training does. Aerobic training, while it can involve higher and lower intensity efforts, generally emphasizes sustained activity at a consistent intensity rather than the alternation characteristic of interval training. Recreational training tends to refer to physical activity done for enjoyment or leisure rather than structured workouts designed to enhance fitness through specific intensity intervals.
